Towards is a reporter that returns the angle that would be the heading of the caller if it was to face another specified agent. For example, if turtle 0 is at the center of the model, and turtle 1 is directly to the right of it, ask turtle 0 [ show towards turtle 1 ] would print 90. Towards reports the absolute angle between the coordinates of the two agents, and will change as the agents move around, but will not change if the headings of the agents change.
